Patent DE-3738897-A1 (DE)
Title: Thermally conductive connecting element for electrical components
Inventor: NENDEL HARTMUT ING GRAD
IPC: H01L23/40
Filed: 1987-11-17
Abstract: Conventional connecting elements, which are constructed as a rigid metal piece, are used for dissipating heat losses produced in integrated circuits and the like. However, as soon as the printed circuit board on which the component is mounted distorts, the heat dissipation deteriorates very considerably. The connecting element 1 according to the invention is produced from a metallic thin foil strip which is continuously wound onto a mandrel and is thereafter stamped with a die. In this case, the foil strip layers 6 are pressed onto one another on one side so that a flat thermally conductive strip 5 is formed which is flexible in its central region 2. The two end regions 3, 4, which are to be mounted on the component and on a heat sink, are reinforced by means of metallic pressure pieces 8, 9, 12, which are at the same time used for mounting. One of the end regions is bonded onto the component, or is fastened by means of a metallic bracket. <IMAGE>

Title: Rotary harrow
Inventor: SEIDL BERNHARD
IPC: A01B33/10
Filed: 1987-12-02

Title: Apparatus for varying the thread guidance on textile machines
Inventor: OFFERMANN PETER PROF DR SC TEC
IPC: D03D3/06
Filed: 1987-12-11
Abstract: The invention relates to an apparatus for varying the thread guidance on textile machines, especially weaving machines, needling machines and further appliances for the production of composite materials. The object according to the invention is achieved in that, in an apparatus for varying the thread guidance on textile machines, having a thread feed and/or model feed and a consolidating device between the thread feed or model feed and the consolidating device, a thread manipulator consisting of a thread guide with at least one thread-guide block arranged on the thread guide so as to be movable in displacement transversely to the working direction, of a distance-changing means assigned to at least one thread-guide block and causing a change in distance relative to a fixed point on the thread guide or relative to another thread-guide block, and of a control device assigned directly or indirectly to the distance-changing means is arranged. By means of such an apparatus, it is possible to vary the local density of the threads over the width of the sheet-like textile structure continuously during weaving or needling, specifically largely irrespective of their density in the thread feed. The flexible control of the thread density at the consolidating point affords new possibilities for patterning or for adaptation to the subsequent force-related load.

Patent DE-3812090-A1 (DE)
Title: Method for optimising the run-up to spin drying, especially in washing machines
Inventor: WIPPERFUERTH FRANZ-JOSEF ING G
IPC: D06F33/36
Filed: 1988-04-12
Abstract: Known washing machines have a sensor-controlled froth-monitoring system. The speed of rotation of the spin drier is temporarily reduced when froth is formed. The spin-drying speed is increased in small steps until the preselected spin drying speed is reached. The method according to the invention makes it possible for the spin-drying speed to be continuously increased without use of a froth sensor system. This results in a reduction in the program flow time. Wash-related parameters such as the amount of wash liquor used, the amount of washing, the type of washing, actual spin-drying speed and the amount of water withdrawn are fed to an electronic system which then varies the run-up period constant (T) and/or the increase in the rotating speed of the washing cylinder in such a way that the formation of froth owing to turbulence in soapy water or rinsing water is prevented. The new method is suitable for reducing the program flow time in washing machines. <IMAGE>

Title: Mortise and tenon joint
Inventor: DREDEN WILHELM VON DIPL ING
IPC: E04B1/26
Filed: 1988-06-15
Abstract: To create a mortise and tenon joint between two wood elements, the mortise (21) provided in one wood element (20) is provided with a widened portion (23, 24) in its lower part. The tenon (11) situated on the other wood element (10) receives a corresponding mating profile with a similar widened portion (13, 14) which fits positively into the widened portion of the mortise. By introducing a slot (16), the tenon (11) is made elastically deformable in such a way that its widened portion can squeeze into the mortise with the tenon pushed together, in order to spread apart again in the lower part of the mortise and thus produce the desired glue pressing force. In this way, it is possible to do without clamps or the like during glueing. <IMAGE>

Title: Storage system reducing risk of legionella in hot water systems - in which water circulates continuously from storage tank to water heater and mixing of waters of different temps. is prevented
Inventor: HAGEMANN HEINRICH
IPC: F24D17/00
Filed: 1989-08-25
Abstract: Water storage is heated preferably to 60 degrees C, and water is drawn off only from a pre-heated water supply, so that mixing of waters of different temperatures is avoided. In order to maintain a stable thermal distribution in the storage tank, and thus to avoid mixing, heated water is introduced below the level of the draw-off point, and water is drawn off only from the upper layers of the storage tank. The storage tank may be divided into a number of separately heated sections. USE/ADVANTAGE - This invention is used to reduce the risk of Legionella infection in hot water storage systems. The proposed process is economical, effectively reduces the risk of infection, and is particularly suitable for installation in systems using hot water storage tanks.
